What has happened to OPG’s coal-fired generating stations?

In April of 2014, Ontario Power Generation burned its last piece of coal to generate electricity in Ontario. This move off coal was North America’s single largest climate change initiative and the equivalent of taking seven million cars off the road. This made Ontario the first jurisdiction in North America to fully eliminate coal as a source of electricity generation.

Atikokan and Thunder Bay generating stations have been converted from coal to biomass, a sustainable fuel.

Lennox Generating Station is dual-fuelled by oil and natural gas.

Lambton and Nanticoke generating stations have been safely removed from service and are being decommissioned.
